1. How far is the intercom distance?
Radio communication does not have the “distance†indicator because ultra-shortwave communication is transmitted through the line of sight. Signals are blocked and interfered with by buildings, hills, forests, and electromagnetic fields, affecting actual distance and quality of conversation. In an ideal state (without any obstruction and interference), the talk distance of a professional walkie-talkie is more than 10 kilometers or more, and the actual talk distance is usually only 3 to 5 kilometers, where there are tall buildings, high mountain blocks, or severe electromagnetic interference in the space. In the future, the call distance may sometimes be short or even impossible to communicate.
2. Can a mass consumer buy a walkie-talkie?
Consumers can also buy walkie-talkies. However, in the past, the purchase and use of walkie-talkies must be submitted to the local radio management committee (abbreviated as “no commissionâ€), to receive a radio license and to pay a frequency occupancy fee. From December 6th, 2001, China's civilian walkie-talkie market was opened, and 400 MHz civilian radios with transmission power less than 0.5 watts were not required to handle any formalities.
3, the intercom can not call?
With the support of the network, the walkie-talkie can be used to make calls. However, if it is only a regular conversation between the individual machines, the function of making a call cannot be realized.
4. Do I have to pay for a call with a walkie-talkie?
There is no charge for talking on the regular walkie-talkie. No matter how frequently you use it, you only need to pay a frequency of tens of yuan for each walkie-talkie each year. If you use a public walkie-talkie, you do not need to pay any fees.
5. Why use a walkie-talkie with frequency limitation?
In order to ensure that the vast majority of users do not interfere with calls and make reasonable use of frequency resources, the National Wireless Regulatory Commission has divided the use of frequencies and specified that different industries use the corresponding frequency ranges. When users purchase a walkie-talkie, they must apply to the local Radio Management Committee for frequency points.
6, how to do the walkie-talkie water?
Many maintenance machines found in the repair were water inlet machines, and it was found that such machines have various degrees of circuit corrosion due to inadequacy of influent water treatment, and the more serious ones cannot be repaired. Therefore, the machine should be promptly filled with water. Disposal, including the immediate removal of the battery, the water is forced out, placed in a ventilated and dry place to dry, and strive to be sent to the maintenance station in the shortest time.
Fast Recovery Diode is a semiconductor device which possesses short reverse recovery time for rectification purpose at high frequency. A quick recovery time is crucial for rectification of high-frequency AC signal. Diodes are mostly used in rectifiers because they possess ultra-high switching speed.
